California high: when you take 20x deep breath causing a and someone embraces you pressing your chest. This will cause a faint that can last to 10 seconds or more. If hyperventilation is used instead of deep breaths, its safe as hyperventilation does not kill, but beware, you must make sure someone holds you before you fall on the floor. a hit in the head can be fatal. Also, this ''game'' will cause you headaches, so not very recomended.
